How is the voice of heart valve changed weak to return a responsibility

summary

Heart valve replacement is actually a technical activity, and future nursing is also very important. Heart valve replacement is the main method for the treatment of middle and late stage rheumatic heart disease. As we all know, the operation is to remove the patient's own diseased valve and replace it with artificial valve, so as to achieve the purpose of treatment. Every year thousands of patients around the world undergo this kind of surgery. Although the operation can make most patients recover good cardiac function, it does not mean that the alert can be removed. The heart changes valve son voice weak is how to return a responsibility son to tell everybody.

How is the voice of heart valve changed weak to return a responsibility

First: at present, most of the artificial heart valves are mechanical valve and biological valve. The two kinds of biological valve are made from the pericardium of pig, cow and other heart materials. Its advantage is that it is not easy to induce thrombosis, and anticoagulant treatment can be done after 3 months. The disadvantage is short life span, only about 10 years of use, patients need to take anticoagulants for life, in order to prevent thrombosis in the heart.

Second, mechanical flap is widely used in China. There are mainly two kinds of anticoagulant accidents in patients with valve replacement: one is cerebral embolism, myocardial infarction, limb artery embolism caused by insufficient anticoagulant dosage. The second is cerebral hemorrhage, hematochezia and subcutaneous hemorrhage of limbs caused by excessive anticoagulation. To prevent these accidents, we must follow the doctor's advice. Within half a year after discharge, the thrombin time was checked every 2 to 4 weeks (every 1 to 3 months after half a year). The INR (international normalized ratio of prothrombin time) should be kept between 2.5 and 3.5. In case of syncope, weakness of one limb or subcutaneous hemorrhage, the INR should be checked in time and the dosage of anticoagulant should be adjusted.

Third: we should also pay attention to the fact that some drugs and foods can affect the efficacy of anticoagulants, such as aspirin, indomethacin, Fenbid, dipyridamole, antibiotics and traditional Chinese medicine for clearing heat and detoxification can enhance the effect of anticoagulants. Animal liver, spinach and other green leafy vegetables, as well as vitamin K, hemostasis and other drugs can weaken the curative effect of anticoagulants, so we should eat less animal liver and green leafy vegetables.

matters needing attention

After heart valve replacement, special attention should be paid to the conditioning, regular check-up in the hospital, to maintain good heart function and the patient's appropriate amount of activity. To calculate the best heart rate of patients during postoperative exercise, the following formula can be used: (170 - age) * 80%. It should be based on the degree that the patients do not appear tired and flustered symptoms. It should not be forced. If they have symptoms of cardiac insufficiency, they should also reduce the amount of activity on this basis and ensure adequate sleep. Sleep is the best rest for the heart.
